Subject [jira] Commented: (HDFS-506) Incorrect UserName at Solaris because it has no "whoami" command by default
Date Tue, 28 Jul 2009 18:01:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12736182#action_12736182

Tsz Wo (Nicholas), SZE commented on HDFS-506:
---------------------------------------------

> Solaris enviroment has no _whoami_ command ...
[In this post|http://www.linuxquestions.org/questions/solaris-opensolaris-20/how-do-i-know-my-currently-logged-on-userid-in-solarisunix-537015/],
they said /usr/ucb/whoam is available in Solaris.

I suggest not to change the existing codes unless whoami is absolutely unavailable.

> Solaris enviroment has no __whoami__ command, so the __getUnixUserName()__ at UnixUserGroupInformation
class fails because it's calling to Shell.USER_NAME_COMMAND which is defines as "whoami".
> So it launched an Exception and set the default "DrWho" username ignoring all the FileSystem
permissions.
